A gene sequence from the common cold virus has worked its way into the Omicron variant of COVID-19. This gene sequence was not in any of the previous mutations of the virus (Alpha, Beta, Delta).
This happened through a process known as switching. The COVID virus invaded a cell and at the same time a common cold virus invaded the same cell. The genes of the two viruses then get mixed up together. This new combination makes the virus more competitive and virulent.
The virus became far more transmissible but perhaps less pathogenic. Patients in South Africa are nor requiring as much oxygen as was needed for patients suffering from Delta.
Omicron is evading vaccines and people who have been infected in the past are being re-infected. Pfizer-BioNTech, has announced that three doses of vaccine are needed to combat Omicron. Research has shown that a third vaccine shot increases antibodies by 25%. They did not say how long those antibodies last. The company is rushing to develop an Omicron specific version of the vaccine which should be available by March 2022.
Omicron is the most transmissible of all the variants of COVID-19 to date. It is 4 times more transmissible than Delta. It has now been detected in 57 countries. Those numbers change by the hour. It will dominate the world stage in several weeks time. We will all be exposed to this variant. Symptoms include, Body aches and pains, muscle pain, headache, tiredness (1 to 2 days), and a slight sore throat. People are not getting a severe cough, or runny nose. These symptoms are consistent with my everyday existence for the past 20 months. A loss of smell or taste is no longer a symptom with Omicron. The fact is that many people will not realize that they have COVID-19 with these symptoms. Most will not go to hospitals and will recover at home. It is important to note however that there has been an slight increase in hospitalizations in South Africa, but it has not been a huge spike consistent with the amazing exponential growth in infections.
Though Omicron looms in the near future, the fact is that Delta is causing a huge spike in hospitalizations and death in states like Michigan and Minnesota. Despite these rising cases and deaths, most Americans are done with the pandemic and have returned to pre-pandemic life styles. Thanksgiving travel rivaled pre-pandemic travel and cases that resulted from all that mingling are just now reaching their peak. People have let their guard down and the virus will take full advantage of that weakness.
Children are the new victims of the virus. 132,000 children have been reported with infections in the last week across the country. Children will be infected by the Omicron variant at an increased rate. Children need to be vaccinated and even boosted if they are eligible. In South Africa 80% of the patients admitted to hospitals and diagnosed with COVID were under the age of 50. This is a younger age profile than existed with the Delta surge.
